Syria is trying to negotiate a deal to prevent punitive action by the United Nations if, as is widely expected, the Damascus government is linked to the Feb. 14 assassination of Lebanon's former prime minister, according to U.S. and European officials.

Over the past month, the government of President Bashar Assad has been inquiring about the potential for a deal, roughly equivalent to what Libyan leader Moammar Gaddafi did to end tough international sanctions imposed for his country's role in the 1988 midair bombing of Pan Am Flight 103, the officials said. Gaddafi eventually agreed to hand over two intelligence officials linked to the bombing for an international trial, a move that began Libya's political rehabilitation.
